<h1 id="全局样式与局部样式"><a href="#全局样式与局部样式" class="headerlink" title="全局样式与局部样式"></a>全局样式与局部样式</h1><blockquote>
<p>使用Vue-cli时，每一个Vue文件变成一个单独的组件，其中可以定义template、script、style</p>
</blockquote>
<p>其中样式分为全局样式和局部样式:</p>
<figure class="highlight xml"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br></pre></td><td class="code"><pre><span class="line"><span class="comment">&lt;!-- Add "scoped" attribute to limit CSS to this component only --&gt;</span></span><br><span class="line"><span class="tag">&lt;<span class="name">style</span> <span class="attr">scoped</span>&gt;</span></span><br><span class="line"><span class="tag">&lt;/<span class="name">style</span>&gt;</span></span><br></pre></td></tr></table></figure>

<p><strong>结论：style加scoped属性，样式就是局部样式,只对该组件有效；不加scoped属性，样式就是全局样式，对所有组件都有效</strong></p>
